So, been trying to research and understand things much better about the truck and I see a lot of positive feedback on getting a blackbear tune and AFM delete and this seems to be something I want to invest in. Any recommendations there with current condition of my truck?

Also, after doing some additional research, I see that some people do a proactive replacement of the torque converter. I don't think I'd do this before my trip, but should I be considering looking for a good transmission shop in the area and doing this sometime next year?
If you can alring for a blackbear tune, DO IT! You won’t regret it! Lol. They are absolutely amazing at what they do. Very professional, reasonable cost and you get a lot of value out of a tune. Even on a stock truck it just wakes up that 6.2, and brings out all the an available power. the transmission part of the tune is so worth it as well. While I don’t have much experience with the 6L80s, I’ve heard they’re reprogrammed from the factory to race up through the gears into over drive as quickly as possible and I’d imagine that leads to a lot of hunting for the right gear when you’re trying to get up and go in drive. Even my 4L65 did it. They can adjust the shift points so it’ll hold a lower gear a bit longer which will make the transmission much more usable and more fun. Plus having the trans not shifting around a bunch in hunting for the right gear will help keep the temperatures down from what I understand and less heat in the transmission is always better lol.

you should create your own thread/post, but the first thing to do is get a scanner that can read body codes and see what the code is.

Yup! I'm splurging for the tune - have already ordered the hardware and hoping to get the process started when I get back into town this weekend!

Any comment on proactively changing the torque converter - I've noticed this in a couple of threads as I've been doing a lot of reading?

Ok, here's where I am now. Had a new to me local shop finish up some work while I was out of town last week. I now have this done as well:

Transmission filter and fluid
Power steering fluid
Differential fluid
Transfer case fluid
Replaced driver's side engine mount
Replace lower ball joints
Replace tie rods
I'm noticing they didn't do the brake fluid

Used OEM fluids and OEM parts except for the transmission pan gasket because it was on nationwide backorder.

With every passing day, the truck is running more and more like new.

The engine mount change has nearly stopped the rough idle completely and I no longer have any hesitation and clunk sound when I accelerate.

Up next:
I had the shop collect my engine oil and transmission fluid (which looked terrible) so I can send to Blackstone.

I have my hardware from @BlackBearPerf to get the truck tuned. Are there any specifics I need to request with this tune? My priority is less on fuel economy and more on the fun of driving the truck.

Big 3/4/5 - which I still need to understand a little better, but I've purchased everything I need to do it.

Finish installing my dashcam

I noticed nobody responded to my question about proactively replacing the torque converter - I'm assuming this is not an issue?

you could do the TC as a pre-emptive but it may be a good idea to have it completely overhauled at the same time with all the other little fixes, you could do it and then 6 months down the road have someting else go wrong and then you are paying labor twice.
just my 2 cents, I tend to be rough and break stuff so that should be considered as well.
